The ability to move from one representation of data to another is one of the key characteristics of expert mathematicians and scientists. Cloud computing will offer more opportunities to create and display multiple representations of data, making this skill even more important in the future. The advent of the Internet led to widespread…

Media--text, images, audio, and video--underwent a transformation from analog to digital formats during the transition from the 20th to the 21st century. Digital media can easily be replicated, downloaded, revised, edited, and reposted, and the implications of this are affecting education, government, entertainment, culture, and society. The…

In higher education, the number of computer projectors in classrooms has doubled every year for the past five years. A similar trend in K?12 education is occurring now that capable classroom projectors have become available for less than $1,000. At the same time, large-screen displays are becoming common in society; a trend being acceleration by a…

Most mathematics teachers agree that technology can be used to promote mathematics teaching and learning. Indeed, the Technology Principle of the National Council of Teachers of Mathematics' "Principles and Standards for School Mathematics" states: "Technology is essential in teaching and learning mathematics; it influences the mathematics that is…

Imagine a business that with great ingenuity and expenditure of resources placed a telephone line in every worker's office, but failed to provide phone receivers for them. A new CEO of the firm would immediately recognize the need to place a phone receiver in every office with a phone line to make those lines usable. This scenario is absurd…

New technologies often assume the form of prior traditions during their infancy. For example, filmed plays known as photoplays were initially produced prior to the development of modern cinema conventions. Similarly, printed books at first assumed many of the characteristics of hand-lettered manuscripts.

In several recent studies and surveys, both beginning and experienced teachers ranked access to a projector as one of the actions most likely to facilitate more effective use of technology in their classrooms. Advances in display technologies now make this increasingly feasible. For example, digital light processing (DLP) technology is one of…

The Center for Technology and Teacher Education at the University of Virginia developed "Kids an Cookies" a free Flash-based materials and software applications to help prepare teachers to use technology to enhance and extend their students' learning of school subjects. Presents the mathematics team set of guidelines to shape the development of…

So far classroom use of the Internet has been limited to asynchronous communication, but virtual conferencing will allow real-time connections between teachers and classrooms separated by continents. This article describes virtual conferencing applications: Chat, audio- and videoconferencing, electronic white boards, application sharing, and file…
